Lesson !
Found World Book for Kids, it was very easy, looked up Llama.  The information as in a simple to understand form and would definitely be helpful to younger students.  World Book Online Reference gave more information at a higher level suited to the students in the middle range of our school.  Both locations had pictures as well as lead ins to other related animals. 
There was an over abundance of information when I looked up Peru on the Reference Center.  The left side of the page gave close to 100 different places to find information on the country in question.  WOW!  While the right side of the page had 7 articles about the history of the country.    This would definitely  be useful  for older students when doing reports.
